Simple Grub2 changes : conf.d style file location configuration recipes partition notation like grub legacy change script boot order by changing numbers os prober (find installs on disks) install even while booted into OS Summary: GRUB 2 has three main parts: 1. /etc/default/grub - the file containing GRUB 2 menu settings. 2. /etc/grub.d/ - the directory containing GRUB 2 menu creating scripts. 3. /boot/grub/grub.cfg - the GRUB 2 configuration file, not editable. update-grub command reads the /etc/grub.d directory and looks for executable scripts inside it. The scripts are read, in the order of their numbering, and written into the grub.cfg file, along with the menu settings read from the /etc/default/grub file. Boot entries come from several sources - the default that comes with the distribution, other operating systems probed on the connected disks and custom scripts written by the user, following a strict syntax. The scripts are written as shell (sh). You can add/remove entries by simply chmod-ing the scripts; no need to delete them. GRUB 2 can be reinstalled anytime you want, even while booted in the OS GRUB 2 targets at the following goals: * Scripting support, such as conditionals, loops, variables and functions. * Graphical interface. * Dynamic loading of modules in order to extend itself at the run time rather than at the build time. * Portability for various architectures. * Internationalization. This includes support for non-ASCII character code, message catalogs like gettext, fonts, graphics console, and so on. * Real memory management, to make GNU GRUB more extensible. * Modular, hierarchical, object-oriented framework for file systems, files, devices, drives, terminals, commands, partition tables and OS loaders. * Cross-platform installation which allows for installing GRUB from a different architecture. * Rescue mode saves unbootable cases. Stage 1.5 was eliminated. * Fix design mistakes in GRUB Legacy, which could not be solved for backward-compatibility, such as the way of numbering partitions. My experience is from Suse 11.0 BTW....
